Calculate the capacitance of a parallel plate capacitor having circular discs of radii `0.05m` each. The separation between the

Correct Answer - `0.69xx10^(-10) F`
Here, `r = 0.05m, d = 1 mm = 10^(-3) m`
Capacitor `C = (in_(0) A)/(d) = (in_(0) pi r^(2))/(d)`
`= 8.85xx10^(-12) xx(22)/(7) xx ((2.05)^(2))/(10^(-3)) = 0.69xx10^(-10) F`

Calculate the capacitance of a parallel plate capacitor having circular discs of radii `0.05m` each. The separation between the discs is `1 mm`.
